MPLAB X IDE v5.35 is a critical version for many developers because it is the final release to include the MPASM assembler
, which was discontinued in versions 5.40 and later. This makes it essential for maintaining legacy projects or working with older 8-bit PIC microcontrollers that rely on absolute assembly code. How to Download v5.35
Since v5.35 is no longer the current release, it is found in the official archives rather than the main download page. Official Archive : Visit the MPLAB Ecosystem Downloads Archive Direct Download Strategy
: If a specific version is not visible on the page, you can often find it by taking a known download link for a similar version and manually changing the version number in the URL (e.g., changing System Versions : The installer is available for Microchip Technology Installation Best Practices Multiple Versions
: You can install v5.35 alongside newer versions (like v6.xx) on the same computer without conflicts. Avoid Importing Settings download mplab x ide v5.35
: When prompted during the first launch, it is often recommended
to import settings from older versions, as this can sometimes cause performance slowdowns. Compiler Pairing
: While v5.35 includes MPASM, it does not include the XC compilers (XC8, XC16, XC32). You must download these separately from the Compiler Archive macOS Catalina (10.15) Users
: Version 5.35 may require a specific patch to run correctly on macOS Catalina due to the removal of 32-bit support in that OS. Microchip Technology Key Features of v5.35 Final MPASM Support MPLAB X IDE v5
: The last version to support the original 8-bit assembler natively. Device & Tool Packs
: Introduces the "Tool Pack" system, allowing you to update hardware debug tool firmware (like for PICkit 4) independently of the IDE. Improved GUI
: Features a docked workstation layout that handles multiple files and projects more effectively than the older "dangling window" versions. MPLAB® Ecosystem Downloads Archive | Microchip Technology

Downloading MPLAB X IDE v5.35 and Developing a Feature
MPLAB X IDE v5.35 was released in late 2019. Unlike some major revisions that introduced sweeping changes to the user interface or project structure, v5.35 represents a point of peak stability. Key features of this version include:
For engineers working on products with long lifecycle support (often 10+ years), freezing the toolchain at v5.35 is a strategic decision to avoid compiler-induced bugs or library conflicts.
MPLABX-v5.35-windows-installer.exe.C:\Program Files\Microchip\MPLABX\v5.35. Do not change this unless necessary.No. ICD 5 and MPLAB Snap require firmware that is incompatible with v5.35. Use v6.00 or later.
